i got a code 43 - faulty knock sensor, low voltage at electronic spark timing circuit.

got the code a while ago and i could only get the check engine light to come on if id been driving for an hour or did a little "hot rodding" ive replaced the knock sensor, everything looks good, and while that was being done i also had a 180* thermostat put in as well. this was 3 days ago. now my check engine light comes on immediatly after its been started and stays on. i pulled the code.. same code 43 as before. i did clear the comp, left the battery unhooked over night, and im not sure what to do now. help??

 

how does it run when it comes on??? big loss of power??

 

no, not really. not as powerful as it should be, but its in need a of a tune up bad. has power... i m still burnin out.
light comes on immediatly after iv started her, and stays on. doesnt seem to run any different though.

 

well i cant remember if this is code 43 or if it is 42 but my ignition module went out and it had very similar symptons to yours....maybe somethin you could look into

 

ignition mod.... is that in the engine bay? or by the steering colum?
my car runs fine, i just want that damn light to go off and it to stop throwin that code.

 

its in the distributor it sits down under the cap....it would give you a electronic spark timing code just now sure which one

sometimes its possible for it to have a bad connection..i would also check to make sure your prom is seated in the ecm properly...

i think ignition modules are a fairly common repair at least once on tpi cars.

 

k thanx, ill check into it. reason i was asking on the location is somone tried to steal my car, its fine now, but my colum is trashed to ****.
